Expanded Metal is made from sheets of solid metals that all are slit and stretched with each stroke of the upper die, forming a raised diamond pattern.
This pattern is called regular or standard. This pattern varies by the gauge and type of material and the size of the diamond.The sheets can also be flattened by rollers for an optional style by pasing them through a cold, roll reducing mill.
Expanded metal also can be manufactured in heavy gauges for applications such as walkways, ramps, and catwalks of all types. Frequently, the heavier gratings and catwalks are used in industrial plants for flooring and stain treads.
Due to the flexibility in materials and the sizes that it can be manufactured, expanded metal has a large application in filtration purposes. Thicker sizes with apertures above ½" also has certain general purpose applications like partitioning and covering for security.
Manufactured in Mild Steel (M.S.), Galvanised Iron (G.I.), Stainless Steel 304, 316 (S.S.) Aluminum ( AL.) from 0.5 mm opening to 50 mm opening in all possible thickness
Expanded metal contains open spaces (the diamond-shaped openings) and material. Open area is the total area of the diamond openings divided by the total area of the sheet or roll of expanded metal and is expressed as a percent. In other words, open area describes how much of the expanded metal is open space. If expanded metal has a 60 percent open area, then 60 percent of the expanded metal is open space and 40 percent is material.
